Detection of mouse cough based on sound monitoring and respiratory airflow waveforms. [PDF]

open access: yesPLoS ONE, 2013
Detection for cough in mice has never yielded clearly audible sounds, so there is still a great deal of debates as to whether mice can cough in response to tussive stimuli.

Human Stress Detection Technologies: An In‐Depth Comparison of Machine Learning Algorithms and Applications

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
ABSTRACT Workload pressure, examination stress, family responsibilities, and a variety of other factors all contribute to an increase in stress in the body. Stress weakens the human mind and body by accelerating several health disorders. Therefore, the number of approaches for early projection of stress plays a vital role in the healthcare sector ...

Preoperative “R wave amplitude variation” on electrocardiogram predicts severe hypovolemia

open access: yesAnnals of Cardiac Anaesthesia, 2019
Preoperative fasting is essential to prevent aspiration and associated complications. However, quite often patients end up fasting for 12 h or more due to changes in the operating room schedules, delays, and postponements.

Quantifying physiological variability and improving reproducibility in 4D‐flow MRI cerebrovascular measurements with self‐supervised deep learning

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 6, Page 2599-2610, December 2025.
Abstract Purpose To assess the efficacy of self‐supervised deep learning (DL) denoising in reducing measurement variability in 4D‐Flow MRI, and to clarify the contributions of physiological variation to cerebrovascular hemodynamics. Methods A self‐supervised DL denoising framework was trained on 3D radially sampled 4D‐Flow MRI data.

Unique Role of Proximal Tubule Dipeptidyl Peptidase 4 on Blood Pressure, Renal Sodium Handling, and Na+/H+ Exchanger Isoform 3 Phosphorylation

open access: yesActa Physiologica, Volume 241, Issue 12, December 2025.
ABSTRACT Background Dipeptidyl peptidase 4 (DPP4) is a transmembrane serine exopeptidase highly expressed in the proximal tubule (PT). While its enzymatic role is well characterized, its non‐enzymatic functions remain unclear. DPP4 physically associates with the Na+/H+ exchanger isoform 3 (NHE3), and DPP4 inhibitors promote natriuresis; however, the ...

Ventilatory chemosensory drive is blunted in the mdx mouse model of Duchenne Muscular Dystrophy (DMD). [PDF]

open access: yesPLoS ONE, 2013
Duchenne Muscular Dystrophy (DMD) is caused by mutations in the DMD gene resulting in an absence of dystrophin in neurons and muscle. Respiratory failure is the most common cause of mortality and previous studies have largely concentrated on ...
